    摘要: An electrode for superoxide anions characterized by comprising a conductive component and, superimposed on a surface thereof, a film resulting from electrolytic polymerization of a metal thiofurylporphyrin/axial ligand complex; and a sensor for measuring a superoxide anion concentration including the same. The electrode for superoxide anions, by virtue of not only the excellent performance of electrode provided with the metal porphyrin complex polymer film, but also the presence of the axial ligand, can prevent poisoning by a catalyst poison such as hydrogen peroxide. Accordingly, in any of in vitro or in vivo environments, this electrode for superoxide anions enables detection of superoxide anion radicals without suffering any influence from a catalyst poison such as hydrogen peroxide. Moreover, quantitative assay of superoxide anions can be performed by the use of this electrode for superoxide anion in combination with a counter electrode or a reference electrode. Thus, this electrode for superoxide anions can find wide applicability in various fields.

    摘要: Internally calibrated pH and other analyte sensors based on redox agents provide more accurate results when the redox active reference agent is in a constant chemical environment, yet separated from the solution being analyzed in such a way as to maintain electrical contact with the sample. Room temperature ionic liquids (RTIL) can be used to achieve these results when used as a salt bridge between the reference material and the sample being analyzed. The RTIL provides the constant chemical environment and ionic strength for the redox active material (RAM) and provides an electrolytic layer that limits or eliminates direct chemical interaction with the sample. A broad range of RAMs can be employed in a variety of configurations in such “Analyte Insensitive Electrode” devices.

    摘要: A method for analyzing a gas includes measuring a concentration of a chemical species of the gas in a measuring space of a gas sensor. The gas sensor has a semiconductor substrate with an electrical circuit and a first thin-film ion conductor that separates a reference space for a reference gas from the measuring space for the gas. The first thin-film ion conductor has a reference electrode that faces the reference space and a measuring electrode that faces the measuring space. The reference electrode and the measuring electrode are connected to the electrical circuit. The measuring of the chemical species includes picking off an electrical voltage between the reference electrode and the measuring electrode of the gas sensor. A partial pressure of the chemical species in the gas is determined by processing the electrical voltage in the electrical circuit by using a stored processing specification.

    摘要: Methods and devices for point of care determination of heparin concentration in blood are described. Cartridges including protamine ion sensitive electrodes (ISEs) and reference electrodes and systems for automatically determining heparin concentration in the cartridges are provided. Some systems add blood to a protamine bolus sufficient to bind all heparin, leaving excess protamine. The excess protamine concentration can be determined by measuring the initial slope of the electrode potential rate of change, and comparing the slope to known protamine concentration slope values In some cartridges, an oscillating pressure source moves the blood-protamine mixture back and forth across the protamine ISE. Some systems also use a second blood sample having the heparin removed or degraded to create a blank reference sample. Protamine ISEs can include polyurethane polymer, DNNS ionophore, and NPOE plasticizer. The polyurethane may include hard segments and soft segments, where both hard and soft segments may include cyclic and straight chain aliphatic moieties having essentially no ester or ether groups. Some hard segments may include methylene diphenyl groups. Some reference electrodes have the same polymer, plasticizer, and ionophore as the measurement electrode, but with a different concentration of ionophore.
